Hi, > RAID 10 (or a striped mirror) will increase the > redundancy of a stripe. Have 4 disks (if using an IDE > RAID controller it's perfect for this), stripe each > set of two and mirror the 2 stripes. You boost your No, you should make two mirrors first and then stripe the mirrors (like you started saying - striped mirror). If you mirror stripes and you lose a disk on each side your whole array is kaput! If you stripe mirrors and you lose a disk on each side your array is still operational! -- Regards, +-----------------------------+---------------------------------+ | Peter Kiem .^. | E-Mail : <zordah@xxxxxxxxxx> | | Zordah IT /V\ | Mobile : +61 0414 724 766 | | IT Consultancy & /( )\ | WWW : www.zordah.net | | Internet Services ^^-^^ | ICQ : "Zordah" 866661 | +-----------------------------+---------------------------------+ My current spamtrap address is est0704@xxxxxxxxxx
